Influence of Plant Growth Regulators on Growth, Flowering and Yield Characteristics of Hybrid Tea Rose cv. Bugatti during Spring-Summer Months
Journal Title: Advances in Research - Year 2017, Vol 12, Issue 6
Abstract
The present investigation was conducted at Horticultural Research Station, Mandouri, BCKV, Mohanpur, West Bengal, India from February 2016 - March 2017 to study the influence of plant growth regulators on growth, flowering, yield and quality of Hybrid Tea rose cv. Bugatti during spring-summer months. The experiment was laid out in Randomised Block Design (RBD) with seven treatments and three replications. The experimental results revealed that GA3 (Gibberellic acid) at 200 ppm + BA (Benzyladenine) at 100 ppm showed maximum plant height (82.30 cm) and chlorophyll content (16.81 mg/g). The maximum secondary shoots (13.37), leaf area (41.45 cm2), stalk diameter (0.53 cm), flowering duration (22.15 days), vase life (7.04 days) were obtained in benzyladenine at 200 ppm. The treatment BA at 100 ppm showed maximum spread, flower diameter at cup shape and number of flowers per plant (yield). The maximum stalk length was under benzyladenine at 200 ppm + gibberellic acid at 100 ppm. The earliness of flowering was seen under GA3 at 100 ppm. The maximum intermodal length was found under GA3 at 200 ppm. Hence, it could be concluded that the highest values on vegetative and flowering parameters as well as flower quality were achieved in benzyladenine at 200 ppm as compared to other treatments.
